You are correct. I caution against it in my classes. One of the real dangers is that couples can be very protective of each other and often will lie after the fact.
I would probably intervene if I thought a life was in danger, so never is a bit too strong for me.
Not good advice whether you are talking about couples or civil wars in Muslim countries. Great advice!
